Answer:
1. This discovery included Pluto in a newly created family of dwarf planets. It also forced the International Astronomical Union to redefine the term planet.
2. The demotion of Pluto to dwarf planet was caused by the discovery of Eris, a minor body that is larger than Pluto. This discovery triggered important events in the history of science. It also proved that there are still many objects to be discovered in the solar system. Therefore, this was a positive development.
3. This discovery was controversial to a small degree because it challenged a widely accepted belief that Pluto was a planet. However, Pluto was discovered less than a century ago, and people showed little resistance to accepting the change.
4.This discovery can be linked to the developments made in astronomy during the Scientific Revolution. It’s somewhat similar to what happened when Copernicus presented his heliocentric theory. He disputed Ptolemy’s accepted theory that Earth was the center of the solar system. Copernicus argued that the Sun was the center and that Earth and the other planets revolved around it. Both discoveries triggered more research in the field of astronomy.

Muhammad is the prophet that is seen as the most important in the Islam, as well as the one that formed this religion. Before Muhammad started to have the revelations and focus on preaching the word of God/Allah, he did had a profession. His profession was a merchant.

Muhammad was active as a merchant in the eastern Mediterranean region in general which was an excellent location for gaining wealth. During his merchant days, he managed to get in contact with lot of Christians, and that influenced him a lot, later influencing his life and the lives of millions of people in a way that he probably didn't even dream of.
Andreas Vesalius founded modern anatomy. His remarkable 1543 book De humini corporus fabrica was a fully illustrated anatomy of the human body. Based on observations he made during dissections, the book overthrew misconceptions in anatomy that had persisted for over a thousand years.
Vesalius was an anatomy professor at the University of Padua and a physician to Holy Roman Emperor, Charles V. At the age of 15 Vesalius enrolled at Louvain University.
In 1540, at the age of 25, Vesalius began working on a fully illustrated anatomical textbook: De humini corporus fabrica – The Structure of the Human Body. It would be his greatest work, Accompanying the illustrations were descriptions of the muscles’ operations. Not surprisingly, given the richness of its illustrations and its shear bulk, The Fabrica was an expensive purchase, intended for physicians, libraries, and aristocrats. Recognizing that others might also be interested in his work, Vesalius simultaneously released a practical, more affordable text with fewer illustrations entitled The Epitome. Most of The Fabrica’s readers were positive about it. It became the go-to book for serious anatomists and physicians. However, some physicians and academics felt threatened by its revelations: they had built their careers on Galen’s work and lashed out at Vesalius.
Having brought himself to the notice of the emperor, Vesalius was appointed physician to the imperial household. He resigned his professorship in Padua, becoming the fifth generation of the Wesele/Vesalius family to be in imperial service.
